To all whom it may concern;-

Be it known that I, LARS CHRIsTENsoN, a citizen of the United States, residing in the borough of Bronx, city of New York, county of Westchester, and State ofNew York, have invented certain new and useful Improvements in Hollow Fireproof Windows with Revoluble Sash, of which the following, taken in connection withthe accompanying drawings, is .a full, clear, and exact specificat1on. My present invention has relation to that class of windows wherein the window-frame and sash-frame are made of sheet metal and wherein one of the sashes is hung in the frame so that it may be revolved or partly turned in order to'open the window to'the corresponding extent. The principal object of my invention is to provide or produce a window of the class named wherein the parts are amply strong and durable and easy to make and afford a thoroughly fireproof window which may be 0 ened when desired and automatically c osed if fire occurs, efiectually securing the opening in which the window is located.

Subordinate objects are to render the revoluble sash safe against accidental displace-' ment, to provide convenient means for opening the sash and holding it in open position at'any desired angle, and to rovide means for locking the sash when in c osed position.'

To accomplish all of the foregoing purposes and to secure other and further advantages in the matters of construction, arrangement, and operation, my improvements involve certain new and useful arrangements or combinations of parts and peculiar features and details of construction, as will be herein first fully described and then pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective view of a window constructed in accordance with my invention and involving my improvements, the upper sash being shown as held in open positlon. Fig. 2 is a sectional elevation'of a fragment on a lane through the upper rail of the upper sas and at right angles thereto. Fig. 3 1s a side view of a fragment of the frame and a section of the glass, showing the manner of sustaining the upper or pivoted sash. Fig. 4 is a vertical cross-section through the lower rail of the Specification of Letters Patent.

In all these figures like'letters of reference wherever they occur indicate corresponding parts.

The window may include any desired number of panes or panels, which may be ofany required size, and While I have represented a window of two sashes, one stationary and one movable, it should be understood that the movable sash may alone be employed in some constructions and that the number of sashes may be increased as may be desired.

A represents a wall of masonry in which it may be desired to mount the window, and B B represent the vertical members of the me- C is the upper horizontal member of the window-frame, and D the lower horizontal member, both intended to restin contact with the masonry and both being made of sheet metal.

The lower sash is shown as complete and stationary within the window-frame." It may have any number of panes and these panes may be of wired or other glass." For convenience each sash is shown as made up of two panes, those in the lower sash being" f represented at E and F. The piece or member G constitutes the upper rail of the lower sash, and it also serves as the base or bottom piece for the upper sash to close against. On its under face it is formed to furnish the outer or weather molding 1), against which the glass is held by a separate stop-bead 0 entering a suitable channel provided for its reception and secured therein by screws, as are other parts.

The stop-bead c on the lower rail D is conveniently made continuous with that rail. For the vertical rails B the weather-beads b for the lower sash are made of separate strips arranged to enter the vertical recesses in rails B, the base of each such strip being extended, as at V, and fitted to receive the glass pane, as also the corresponding stop-bead 0 At this part the holding-serews d are made to pass through the weather-molding and the stop-bead and into the vertical rail B, thus conveniently securing all together.

The upper sash is mounted so as to turn on a horizontal axis at or near the middle of its length, and for this purpose the sash is supplied on each side with plates H H, each having a projecting trunnion, as H, of ample strength calculated to reach almost to the line of the window-frame, the plates being secured upon the sash by suitable bolts. To receive the trunnions H, plates, as H bearing open trunnion-beds H are bolted on the sides of the window-frame at the proper points. The sash being adjusted to place will revolve on the horizontal axls to the extent permitted, and thus the window may be opened. These windows being generally of considerable size are subjected to considerable air-pressure, and it is important that they may be so mounted and secured in place as not to be liable to be displaced by wind currents or by other force, and I therefore supply a locking-piece H, which fits above the plate H and over the end of the projecting trunnion, being located and secured after the sash is in place and being bolted to the window-frame. To dismount the sash, obviously it will be necessary to first remove the lockingpiece. The separate lockingpiece being in place on one or both sides of the Window affords security against accidental displacement of the sash, and it is easy and cheap to construct and a ply and does not interfere in any way wit the desired movement of the sash upon its axis.

To secure the sash in its closed position, it is'sup lied with a spring latch-bolt, as 1, arrange to engage a asp I, secured upon the window-frame. The bolt I is provided with a convenient projecting ring, as 1 and connected with this is a hand-cord L by which the latch-bolt may be retracted and the sash turned on its axis to open the window as may be desired. A notched plate L is applied on the top rail of the lower sash and serves as a convenient means for securing the hand-cord at any desired point, so as to hold the sash open. For this purpose the hand cord may be conveniently knotted, as indicated in Fig. 1; but the particular means of securing the cord to this plate are not essential and may be changed at pleasure.

Fireproof windows of the general class to which this invention relates are re uired to be so arranged that in case of fire in t 1e vicinity of their location they will if left open antomatically close to prevent draft or the passage of flame or undue heat. The upper sash belng arranged to revolve about a line through its middle, I make the lower part heavier than the up er by fixing a suitable weight, as K, within tie lower rail of the sash. This weight will vary according to the size of the window 3 but it is always to be suflicient to cause the sash when free to swing on its axis from an open to a closed position. When the cord L is made fast, it overcomes the tendency of the weight to close the sash. The upper end of the hand-cord being applied in connection with the ring I of the latch-bolt serves to open that bolt, as well as to pull the up er part of the sash down and to make the sas fast in open osition. To connect the cord with the ring, employa metallic loop L, which is easily slipped through the ring,'thc loop being supplied with separate branches, as L L, bent and perforated at their lower ends to receive the cord 1, which latter is conveniently knotted in place, as shown in Fig. 10. The branches L L are applied to the loop L by an easily fusible solder or material, and when this is subjected to heat, as in the case of a fire, the branches separate from the loop, and the sash is then free to be automatically swung or returned to its closed position, in which position it is automatically locked. This means for releasing the sash is simple and effective and obviates the necessity of any complicated apparatus for this purpose.

M and N are glass panes in the upper sash, of which any number may be employed. The upper rail C of the window-frame is bent so as to afford a projecting stop 0, against which the swinging sash may close, and to secure uniformity the vertical members of the frame are similarly fashioned, as at c; but the sash is made to swing between and clear of the parts 0. The vertical members B on the opposite side are also bent so as to project in a similar manner, as at 6 leaving between the parts 6 and c the vertical angular recesses before referred to. The lower sash is fitted in these recesses, as before explained, and the upper part of the frame adapted to receive the revoluble sash by additional parts or pieces located and secured in these recesses. These pieces, which are also made of sheet metal, are represented at 0 (see Figs. 6 and 7) and are secured in place by suitable screws, as f f, of which the heads vertical sides at the parts above the hingeaxis, so as to form an angular recess, as at g, and below the hinge-axis being carried out and back and returned or doubled, so as to 4 form an angular recess, as at g, the open part of the window-frame.

- of which faces in the direction opposite that of recess g. The purpose of these recesses is to accommodate corresponding projections formed on the movable sash, which projections shut into the recesses when the sash is closed, and thus insure a close joint between the sash and window-frame to exclude aircurrents and dust and to insure against the passa e'of flame. The vertical rails P of the mova le sash are also peculiarly formed, the part above the hinge-axis being bent and doubled back, so as to form a projection or li h, arranged to enter the recess g, and below t e hinge-axis being bent and doubled back, so as to form a projection or lip h, calculated to enter the recess g. The projections or lips form the outer walls of recesses in the sash members, into which the corresponding outer walls of the recesses in strips 0 enter, as will be seen from the drawings, so that the vertical joints between the sash and the window-frame are rendered doubly secure. The upper rail of the movable sash is composed of three principal parts, of which the outer part,

i, Fig. 2, forms the weather-bead and the inner part i forms the inside stop-bead for the glass, the material of the part i being extended u and doubled back, as at lc, to form a strip. or coverin the joint between the sash and the lower f ace of the upper member Between the parts 'i and i is a third piece 4?, the top of which is extended on each side to rest upon the adjacent parts, as indicated. This third part or piece '8 is in its main portion of about the same thickness as the glass, and it affords a suitable parting strip, the three parts after the glass is in place being properly secured together by long screws, as at Z, which reach through parts i and t and into part 'i.

The lower rail of the movable sash is conveniently made of two pieces bent and interlocked, as indicated, the material of the rail on the exterior bein extended down and bent and doubled bac to form a strip m for covering the joint between the rail and the upper member of the lower sash, andit will be seen that this joint is doubly protected, same as the joint between the upper sash-rail and the upper member of the window-frame.

From a consideration of the construction and arrangement of the improved fireproof window it will be apparent that the lower stationar sash may be omitted or that the revoluble sash may be used'above or placed below the stationary one and that other dispositions of the sashes may be made by making only obvious changes in the arrangement of parts and without departing from the invention. The improved window is found to answer all the purposes or objects hereinbefore alluded to.
